Breaker tripping when the charger and well pump run together
Why it happens here
Many Mt. Enon homes run a well pump and a septic aerator on the same 100-amp service. Adding a 50-amp charger pushes the total past what the panel can deliver, so the main breaker trips. The homeowner often blames the charger when the real issue is the service size.
Our approach
We run a load calculation that includes the well pump and aerator, then either upgrade the panel to 200 amps or install a load management device that sheds the charger when the pump runs. That solves the problem without a full service upgrade in most cases.
